Two types of epoxy functionalities were examined: aliphatic and cycloaliphatic. Obtained polymeric epoxy-functionalized ladder-like polysilsesquioxanes were cationically photopolymerized under UV irradiation over glass and plastic substrates. Obtained cross-linked films were examined as hardcoating materials as their thermal, optical, mechanical, and barrier properties were studied. These materials showed superior thermal properties (T-d > 400 degrees C), high optical transparency (>95%), high pencil hardness (4H-9H), low dielectric constant (3.0-3.6), and good barrier properties (WVTR < 10(1) g m(-2) day(-1), OTR < 10(2) g m(-2) day(-1)).
